HP / Agilent 11582A Coaxial Attenuators Set

The HP/Agilent 11582A Coaxial Attenuators Set comprises four fixed attenuators (3 dB, 6 dB, 10 dB, 20 dB) engineered for precise signal attenuation in RF and microwave applications. Each unit uses thin-film tantalum nitride resistive elements on sapphire substrate, delivering flat frequency response and low SWR across DC to 18 GHz. Type-N connectors and 50-ohm impedance ensure compatibility with standard laboratory and system integration setups.

## Technical Specifications

• Attenuation values: 3 dB, 6 dB, 10 dB, 20 dB
• Frequency range: DC to 18 GHz
• Connector type: Type-N (Male/Female), stainless steel
• Impedance: 50 ohms
• Maximum RF input power: 2 Watts continuous
• Maximum SWR: 1.5:1
• Individual model: Agilent 8491B

## Key Features

Thin-film tantalum nitride construction on sapphire substrate ensures attenuation accuracy and minimal variation across the full frequency band. The 3 dB attenuator achieves ±0.20 dB accuracy from DC to 18 GHz; higher attenuation units deliver comparable precision across their specifications. Flat frequency response and low SWR minimize reflections and signal distortion in measurement chains. All four attenuators arrive in a walnut accessory case for protection and organized storage.

## Typical Applications

• Calibration laboratories requiring attenuation standards
• RF and microwave test benches for signal conditioning
• Power level management in complex systems
• Signal attenuation in sensitive measurement setups
• Laboratory environments demanding repeatable, accurate control

## Compatibility & Integration

Type-N connectors provide direct integration into standard 50-ohm RF systems and test equipment. The 2 Watts maximum input power rating supports both low-level measurement and moderate-power applications. Low SWR specification ensures minimal impedance mismatch effects and maintains signal fidelity in cascaded measurement configurations.
